Philosophical Quotes as curated by my Parkour buddy

I recently reconnected with a good friend I hadn't seen since Uni days, a good 7 years ago. We bumped into each other at Parkour, its seemingly no accident that we've crossed each others paths because we might be on the same journey.

Quotes from my friend's Facecrack:

"It is not the critic who counts; not the man who points out how the strong man stumbles, or where the doer of deeds could have done them better. The credit belongs to the man who is actually in the arena, whose face is marred by dust and sweat and blood; who strives valiantly; who errs, who comes short again and again, because there is no effort without error and shortcoming; but who does actually strive to do the deeds; who knows great enthusiasms, the great devotions; who spends himself in a worthy cause; who at the best knows in the end the triumph of high achievement, and who at the worst, if he fails, at least fails while daring greatly, so that his place shall never be with those cold and timid souls who neither know victory nor defeat."
-Theodore Roosevelt

"Life is 10% of what happens to me and 90% of how I react to it."
- John Maxwell

"What lies behind us and what lies before us are tiny matters compared to what lies within us."
- Walt Emerson

"It is not the strongest of the species that survive, nor the most intelligent, but the one most responsive to change."
-Charles Darwin

"Revenge is a poison meant for others that we end up swallowing ourselves. "

"Empty your mind, be formless, shapeless - like water. Now you put water into a cup, it becomes the cup, you put water into a bottle, it becomes the bottle, you put it in a teapot, it becomes the teapot. Now water can flow or it can crash. Be water, my friend."
-Bruce Lee
